rIhis invention relates to improvements in bunch-builders for winding machines. yIt is particularly related to bunch-building devices of the type shown and described in U. S. Letters Patent No. 1,084,459, dated January 13, 1914.

A principal object of the vpresent improvement is to provide a device of the type 'specified which is capable of winding a more extended or wider bunch containing a greater yardage of yarn than that produced with the device of the prior patentabove referred Another object of the improvement is to provide a device of the type specified which is adjustable to wind bunches of different widths containing more or less yarns in accordance with the requirements for any particular type of loom.

Another object of the improvement is to provide a device ef the type-specified which will wind a firmer and more stable bunch sov 'that the yarn will not become loosened and Slough off before it is'fully unwound from the bunch. n Another object of the improvement is to provide a. device of the type specified which is simple ineonstruction and adapted for use with practically all types of winding machines without alteration in the arrangement of the mechanism thereof. e

Further objects of the improvement are'- set forth in the following specification which vdescribes a preferred embodiment of the invention as illustrated in the accompanying In 'the drawings:

Fig. 4 is a further detailed view of the same showing the means for mounting the auxiliary guide; and

Fig. 5 is a fragmentary view of a portion of the automatic operating-mechanism lfor the yarn-releasing member which disengages the yarn from the auxiliary guide.

In the prior patent above referred to the bunchbuilding device comprises automatif ca-lly-operatedlmeans adapted to engage and hold the yarn at the commencement of the winding of a cop or bobbin` to limit its extent of traverse whereby to build a relatively narrow bunch on the bobbin or cop receiver. This -means consists essentially of a swinging arm having -a-notch or guideway through which the yarn draws to lead it on to the bobbin while restraining it from being traversed to any considerable extent longitudinally thereof, and automatically-operated means for swinging the arm out of position yarn whereby it may be traversed to the full extent to build the service ,winding on the bobbin. In the present improvement I make after a predetermined interval to release the l fixed relation to restrain the yarn from be- 'y ing traversed I employ means engaging the yarn and adapted. to be reciprocated from the winding machine to impart a restricted traverse to the yarn during the buildingof the bunch. VIIhe automatically-operated i means acts to release the yarn from the primary traversing-means at the completion of the bunch whereby the yarn is thereafter traversed to the full extent during the service Winding. t

Referring first to Fig. 1 of the drawings, I have 'here illustrated a rotating windingspindle 2 and a reciprocating traverse-bar 3 of the same'general arrangement as that disclosed inthe prior patent above referred to. The winding-spindle 2 is adapted to` 'rotatably support `a wooden bobbin or yarn receiver.- B which may be of any ysuitable 4form as generally employed in feeler the` shuttles of automatic or' looms. In such looms the feeler acts to ef mi j ` forward to build the fect a change of filling when the yarn has been woven fof from the bobbin down to the preliminary winding or bunch, the bunch being designed to provide suilicient yarn to run while the change is being made whereby to prevent fmis icks'in the weave. In the modern type o filling-replenishing loom' a bunch of relatively wide extent is required in order that the feeler may properly coact therewith when the service winding is exhausted to effect replenishment of the shuttle before the yarn in' the bunch has run out. As before stated, my present improved bunchbuilder is adapted for Winding this particular type of bunch on the naked bobbin or carrier and the width of the bunch and the amount of yarn contained therein may be reg-l ulated in accordance with requirements through adjustable means as'later described.

vIn the Well known type of winding machine as herein illustrated the yarn is traversed on the bobbin by means of a threadguide 4 carried on the bar 3. The thread-guide 4 is reciprocated with the bar 3 to the extent required to deposit the service winding on the bobbin and the guide is advanced longitudinally of the bar whereby to progressively step the layers bobbin with a cylindrical body and a tapered nose or delivery end as illustrated by the dot-and-dash lines in Fig. 1.- In some cases the winding may be in the form of a cop or quill supported Aon a paper or fiber tube, as'distinguished from the form of bobbin herein illustrated as built up on a wooden carrier.

` The means for rotating the winding spindle 2 and reciprocating the traverse-bar 3 are not herein described and illustrated as they construction and arrangement as commonly employed in theart. The traverse-,bar 8 may comprise two connected sections 5 and 6, the main portion- 5 being mounted to slide in a bearing 7Y and I projecting from the front ofthe frame of the machine in parallel relation with the axis of the winding-spindle 2. .The threaded seci tion 6 of the traverse-bar is joined to the section 5 by means of a pin-and-slot connection shownat 8, whereby to. adapt this portion1 of the bar to be displaced laterally to-` ward the winding spindle 2 in the manner and for the purpose as later explained. The outer. end of the section 6 slides through a sleeve or bushing 9 which is swivelled in a fixed e bearing 10 to adapt this portion of the bar to swing out of alignment with respect to the portion 5.

The thread-guide 4 is carried on a forkedarm or yoke l1 having suitable bearings 14 enclosing the bar 6 to adapt it to pivot thereyon and to slide longitudinally thereof. The

guide 4 is preferably made as a separate element constructed of porcelain o-r other vitreous material and having an extended threadreciprocating traverse-v way or lguiding-groove 12 through which the I' yarn draws. The thread-guide 4l is advanced along the bar 6 by means of a propelling nut l5 arranged between the legs of the forked-arm or yoke 1l and adapted to engage the threads on the bar. The nut 15 carries acontact-Wheel or disk 16 which is adapted to make contact with the ,layers of yarn deposited on the bobbin, whereby it is rotated intermittently therefrom'at the end of each rearward traverse of the guide 4. `This intermittent rotation of the contactwheel 16 turns the nut 15 to gradually feed the thread-guide 4 outwardly alono the traverse-bar to cause the layers of winding to be deposited in progressively advanced relation in the manner well known to those versed in the art. 'At the start of the winding the first layers of yarn are wound on 4the naked tube or bobbin and in order to bring the contact-wheel 16 into proximity 4therewith the rearward end of the traversebar section 6 is displaced laterally toward the axis of the winding-spindle. Thislateral displacement of the traverse-bar section 6 to adj ust the contact-wheel 16 toward the wind- 'ing spindle is effected by means of a follower 17 which bears against the inclined edge 18 of an arm or finger 20, designated the copv ber 21, s'ee Figs. 2 and 3, which has bearings 22 surrounding the rod 6 at the sidesof the bearings 14 for the thread-guide arm 11. The follower 17 engages the rearward end of the cop-former 20 to maintain the end of the section 6 of the traverse-bar in the position illustrated in Fig. 1. As the thread-guideadvances along the bar-section 6 the follower 17 slides outwardly on the inclined edge 18 v of the former 20, thus permitting the bar-section 6 to gradually .swing away fromithe winding-splndle until eventually it assumes a position in alinement with the An'iain section 5. In this way the heel or foundation for the winding is built up at the base of the bobbin and thereafter the two parts of the traverse-bar are maintained in alinement te cause the contact-wheel 16 to engage with the i yarn mass at its point of greatest'diameter during the building of the conical layers of winding which` form the cylindrical body of the bobbin. The above described construction and arrangement of the winding mech'- anism are well known and in common use and therefore need no further explanation herein.

In the bunch-builder of the prior patent above referred to the yarn or thread feeding to the thread-guide is diverted in its course tothe Winding-spindle by leading it through the restraining means which holds it from bel Lenaerts ing traversedby the guide. v ln the present improved device instead of restraining the yarn by ineens of a relatively fixed arm the strand is caused to lead from the thread-guide through an auxiliary guiding element which is removed at some distance trom the winding-spindle. rlhis auxiliary guiding element 25 may be contracted as a wire arrn orlinger connected to reciprocate with the guide 4. As shown more particularly in Figs. 2 and 4 .of the' drawings, the yoke 2l which straddles the bearings 14 "l'or the guide-arm il projects downwardly from the bar 6 in two opposite inclined legs 26 which are connected at the bottom by a cross-"strip 27 forming ai step or mounting for supporting the auxiliary guide-arm 25. The terminal portions of the legs 26 are .provided with a hook or loop 28 which straddles a fixed rod 29 constituting a track or guideway therefor-to maintain the yolre 2l in vertical relation.

The auxiliary guide 25'n1ay conveniently be constructed in the forni of a wire arno having a flattened plate 30 at its rearward end adapted to seat on the step 27 in position be tween the legs 26 of the yoke 21, see lligs. 3 and4. ln the plate 30 are suitable holes 3l,

. any one of which may be engaged by a bolt 32 to fixedly secure the guide 25 in position on the yoke 2l and to adapt it for adjustment to regulate its operative length for a purposel as later explained. The outer end jof the wire arm or guide 25 is bent into od-set relationwith respect to its main length andjcurled around to Jform ar loop 33 adapted to re 'ceive the strand of yarn or thread y to direct it on to the barrel ol the bobbin B. lt will be noted by reference to Fig. l of the drawings that the loop 33 on the guide-arm 25 is disposed at some distance away from the windingspindle so that as the auxiliary guide is traversed with the thread-guide 4 the yarn will extend in a free length between the point at which it is guided and the surface onwhich it is being wound. Consequently,v the strand will have certain amount of play .between the auxiliary guide and the bobbin so that the extent to which it is traversed on the bobbin will be less than the full extent ot movement of the guide, as will later more fully appear from the explanation of the operation of the device. It will be observed from Fig. 2 of the drawings that the strand y leads up from a source of supply, not herein illustrated7 and passes through the guiding groove `12 in the thread-guide 4 before it is led f through the loop 33 inthe auxiliary guide25. The yarn is threaded through the guides in this manner at the start of the winding, butreinains engaged with the auxiliary guide 25 only during the winding ofthe bunch on the i bobbin, being thereafter released to feed from the main guide 4 direct to the bobbin.

rlhe means for releasingthe yarn from the auxiliary guide 25at the completion of the.

illustrated in Figs. l and 2, it comprises essentially a curved linger or sickle-shaped arni 35- wliich is normally held away from" the path of the yarn during its traverse by the auxiliary guide 25 and 1s shifted or thrown into position to act on theyarn to disengage it from the guide loop 38. The releasing lin* ger 55 may bel operated from any suitable instrumentalities, and conveniently l make use oi the automatic mechanism shown in the prior patent above referred to as employed ior shitting the yarn-restraining ineans. The automatic operating-mechanism may be contained in a casing 36 suitably attached to the trarne 18 of the winding machine. ln the 'present embodiment of the'invention the rel'the casing 36 and has al right-angled extension or arrn 42 whiclinorniallybears against the periphery oi' a rotatable cani 43.r .The cam 43 isjournaled on a stud 44 and carries with it a ratchet wheel45 having a series ol teeth 45 extending throughout a portion of its circumference and terminating at 'oneend in a radial projection'or stop-nger 4?. The stop-finger 47 is normally engaged by a pawl 48 which is pivoted on the pivot-stud 4l for the lever 40. A coil spring 50 surrounds the bearing stud 44 for the carn-43 with one end hoolred'through afhole yin the cam so that normally it tends to rotate the earn and ratchet 45 in a clockwise direction, the extent of this rotation being limited by the engagement or; the pawl 48 with the l,det'ent or stop-inger 4 The ratchet 45 is rotated in a contradecirwise direction by means ol: a pawl 51 which engages successively kwith its teeth 46 during the reciprocation of the pawl from an arm 52.y As the ratchet turns 'the lirst pawl- 48 engages with its teeth 46 to revent retrogressive movement thereof, th being connected by a spring 53 to hold them in engagement with the teeth. A linger 62' on the pawl 5l is adapted to be engaged by the side of the lever 40 to release the pawl from the ratchet 45 when the lever is manually returned to first position.

The pawl 5l is pivoted to the arm 52 by means oli a stud 54, while the arrn itself is rockably mounted on astud 49 screwed .into the lever 40.. The arm 52 reaches across one end of the casing 36 and slides in a slot 55 lli-10 e two pawls l formed inthe bent up end of the latter. A 4

'- its arm 42 is released from Vthe periphery vus of` the cam 43 in the manner as later explained. The outer end of the'arm 52 carries a plate or bumper 58 adapted to be engaged by the side of the arm 19 which connects the former 2O with the end ofthe traverse-bar section 5;. As the bar 5 is longitudinally recip- =rocated the arm'19 of the former 20 comes into engagement with the bumper 58 at each rearward stroke of the bar, thereby acting to rock the arm 52 to cause the pawl 51 tol turn the ratchet 45 through the distanceof one tooth. As the ratchet is turned in a contraclockwise direction the' pawl 48 'engages successively with its lteeth to prevent it from turning back andthe cam 43 is rotated with the ratchet while the arm 42 of t-he lever 40 rideson its periphery. Referring to Fig.

' 5 ofthe drawings, it is to be noted that thecam 43 has a cut-away section at 59 to allow the end of the arm 42A to slide across its axis. It isalso to be noted that the pawl 48 has a finger 60 bent down to engage against the side of the arm 42, so that when the lever is swung backinto its initial position' the pawl' will be released from the ratchet to allow the latter to be turned back until its detent 47 engages with the end of the pawl. The

method of operation of the complete devicel will now be explained in detail.

' -To prepare the machine for Winding the thread-guide 4 is adjusted in position adjaycent the butt end of the bobbin B by sliding the yoke 11 back tothefrearward end of the traverse-bar section 6, the' nut 15 being released from the threads on the bar in the usual manner for .this purpose. justment of the thread-guide causes the follower 17 to slide up the inclined edge 18 ofv the cop-,former 20 so that the end of the bar section 6 is swung inwardly toward the axis of the winding-spindle 2. This brings the periphery of the contact-wheel 16 vin imity to thesurface of the barrel of the bobbin B so that it will be caused to contact with the first llayer of winding wound on to the barrel. The strand y of thread or yarn is led up from its'source of supply, carried through the groove 12 inthe thread-guide 4 and thence drawn out around the loop 33 at the end of the auxiliary guide 25. The lend of the yarn is then led back to the barrel of the bobbin B and suitably secured thereto by tying or winding it therearound. l

The Winding machine is started to operlate and the winding-spindle 2 rotates the bobbin B to wind on the strand as it feeds from the auxiliary ide 25. Concurrently with the rotation o the spindle 2 the traverse-bar 3 is reciprocated to cause the threadguide 4 'to traverse backl and forth longitudinally of the bobbin.\ The auxiliary guide x 25 being carried with' the guide 4 is thus also traversed longitudinally of the bobbin B,

proxbut, since, as before explained, the -strand y leads from the guiding loop 33 to the bobbin B in a free length its traverse on the barrel of the bobbin will be.4 somewhat less than the full extent of reciprocation ofthe threadguide 4 as ,indicated by the dot-and-dashv lines in Fig. 1; the full lines'representing the position of the guide 25 at the end of its outward traverse and the dotted lines' illustrating its position at-the endr of its inward traverse. The strand 3/ is thus caused to Wind on to the bobbin in layers of restricted 4 ,traverse to build a bunch indicated by the reference character b.

During this-initial winding of the bunch on the bobbin B the yarn-releasing finger 35 rem'ainsxed in the position shownv by full lines in Fig. 1, the finger extending' `downwardly toward the axis of the vwinding-spindle 2 as shown more particularly inl Fig. 2, but being out of the path of the length of'yarn leading from the guide 25 to the bunch. The yarn-releasing linger 35 is held in this position by engagement of the arm 42 on the lever 40 with the periphery of the cam 43. As .the bunch winding proceeds the arm 52 is operated vfrom the reciprocating movement of the traverse-bar 3 to cause it to actuatc the pawl. 51 to intermittently rota-te theratchet 45 and thereby the cam 43. At each rearward stroke of the traverse-bar section'5 the arm 19. of the former 20 strikes against the bumper 58 to swing the arm 52" l to rthe left as viewed in Fig. 1, andas the bar 5 moves in the opposite direction the spring 56 returns the arm 52 back to rst position whereby to engage the pawl 51 v with another tooth on the ,ratchet.- After a predetermined number of oscillations of the arm 52 the pawl 51 will have turned the ratchet 45 suliiciently to bring the cut-out portion 59 of the cam 43 into the position illustrated in Fig. 5 of the drawings, and at this point the arm' 42 on .the lever 40 is allowed to slide across the axis of the cam as thelever is rocked under the tension of theA spring, 56. Through this action of the automatic mechanism the yarn-releasing .finger 35 is swung back .to the position illustrated by dash lines in Fig.l 1.l

The release of the 'arm 40occurs at the end therefore lift the strand out of t eloop 33 to' iireeit from the gui 25. Now as the traverse-bar 5 slides outwardly toward the end of the'windingspindle 2 the strand y l) of the next bunch wound.

will slide oil from the end of the finger 35` and the loop or bight of yarn extending between the thread-guide 4 and the bobbin B will thus be released. As the slack in the loop f bin with the full extent oftraverse Aoi the guide. The Amachine will thereafter continue to operate to lay the yarn on the bobbin with the full extent of traverse to build the service winding forming the main body oi the bobbin which is constituted by a series of conical layers stepped progressively forward toward the tip end of they spindle 2.

lllhenthe bobbin is completed in the form illustrated by dot-and-dash lines .in/Fig. l

it is defied from the spindle 2 and an empty carrier placed thereon. rlhe thread-guide 4 is then returned to its initial position on the traverse-bar 3 in the manner as before eX- plained and the yarn-releasing finger 35 is adjusted out of range of action. ln setting the yarn-releasing finger 35 the lever 40 is' rocked manually into the position shown in Fig.. l where it is held by the return of the' cam 43 to rst position. The return of the cam 43 is edected by the release of the pawls 48 and 51 from the teeth on the ratchet 45' under the rocking action of the lever 40. As the lever 4() is swung back into -irst position the edge of its arm 42 engages with the lug 60 on the pawl 48 to rock the pawl away from1 the ratchetv teeth 46. Concurrently therewith the outer end of the lever 40 engages with the nger 62 on the pawl 5l to also release this awl from the teeth 46. As the lever 40 is held for 'an instant to cause this release of the pawls 48 and 5l the ratchet 45 is turned bach under the tension of its spring until itsstop-nger 47 strikes against" the end of the pawl 48. The lever 40 can then be released and the parts will .assume and be held in cooperative relation as illustrated in Fig.

'l to provide for the automatic operation of theyarn-releasing finger 35 at the 'completion It will be observed from the above that the present improvement providesa simple and -ecient mechanism for effecting the winding of a bunch on the bob-bin having a suitable width and the .proper length of yarn contained therein in accordance with the require-4 ments of present type feeler looms.

To vary the width of Athe bunch the auxiliary-guide arm 25 may be adjusted on its carrying-member or yoke 21.130 set the guiding-loop 33 at a-greater or less distance away from the axis of the winding-spindle 2. It is obvious 'that-'as the guiding-loop 33 is moved away from the spindle 2 the rangethe spirit of play of the' yarn leadingfrom the^loop to the bobbin will be increased so that the extent of traverse of the yarn on the bobbin will be correspondingly restricted. On the other hand, as the guiding-loop 33`is adjusted toward the winding-spindle the yarn will have less play betweenthe auxiliary guide and the bohbin and therefore its traverse will be increased and the bunch wound with a more extended' width. The greater the eX- tent of the bunch the greater the length of4 yarn contained therein, so that in thisway the yardage in the bunch winding may be Controlled as desired. As a further means of reculating the amount or length of yarn wund int-o the bunch the ratchet 45 may be adjusted angularly of the cam 43 to require a greater or less number of reciprocatioris of .the traverse-bar 5 before the lever 40 is released. The yarn-releasing finger 35 may therefore be caused to act after any certain number of reciprocations of the traverse-bar 5 to disengage the strand from the auxiliary guide after a predetermined'number' of revolutions of the winding-spindle 2.

As a further feature ot improvement the present device operates to form a firmer and more stable bunch which will not Slough ed 1. ln a winding machine, the combinationv of means for initially winding yarn on a bobbin with a restricted traverse to build a bunch, means for laying the yarn with alonger traverse to build the service winding, and mechanically-actuated means operated upon the completion of the bunch to shift the yarn from the bunch-winding means to the service-winding means.
